AI Technical Summary
Technical Problem
Inkjet printing on less-ink-absorbent or non-ink-absorbent recording media faces issues with insufficient ink fixability and image fastness, leading to problems like transfer and peeling, especially in rotary printing and sheet-fed printing.
Method used
An aqueous ink composition containing an acid-modified polypropylene resin and oxidized polyethylene wax, along with a color material and aqueous medium, provides enhanced setting properties and image fastness on less-ink-absorbent or non-ink-absorbent media.
Benefits of technology
The composition achieves sufficient setting properties and image fastness on less-ink-absorbent or non-ink-absorbent media, preventing transfer and peeling, while suppressing defects like mottling and white streaks.
